Dinoderus minutus

It is currently established as a native species in many Chinese cities including Beijing, Fujian, Guangdong, Sichuan, and Hong Kong among many.

The bamboo borer is considered native in India, Indonesia, Japan, Malaysia, Philippines, and Sri Lanka.

Figure 1: List of introduction sites and years for the bamboo borer[9][7][8][10] Currently, Dinoderus minutus can be found on most continents.

The bamboo borer is also considered native in Hong Kong, India, Indonesia, Japan, and Malaysia.

The borer can still be found in many parts of Europe including Czechia, Germany, Italy, Norway, and Sweden.

Cuba, Trinidad and Tobago, and the United States constitute the North American range of the bamboo borer.

[8] Australia, Fiji, New Zealand, Papua New Guinea, and Solomon Islands all carry bamboo borer populations.

The borer can easily be transported across the globe through the trade of domestic and imported bamboo products.

[11] The above ground structures (shoot, trunk, branches) and wood of the bamboo tree are the only parts that borers will attach to.

[3] Clothing, footwear, personal possessions, and land vehicles have also been identified as pathway vectors for the spread of Dinoderus minutus.

Adult borers are charged to dig 15 to 20 mm tunnels in bamboo wood for females to lay their eggs (approximately 20 at a time).

[3] Additionally, the bamboo borer can withstand relatively cold temperatures and doesn’t perform overwintering.

Determining the better methods for pest control depends on factors such as severity of infestation, location, potential of reinfestation, and cost.

Phytosanitary methods mostly relate to international trade and transport as bamboo borers have the potential to cause important damage to plants when introduced in a new environment.

If borer infestation symptoms are detected, pest control such as fumigation and heating often represent safe alternatives.

One of the methods simply involves soaking the wood in water which suffocates the beetles, but it takes a long time and it risks blackening the culms.

[17] Other methods include flame heating, exposure to sunlight, microwaving, and advanced infrared technology.

[3] Chemical treatments involving pesticides and preservatives have been widely used to control pest post-harvest.

The 5% copper-chrome-arsenic composition, 5-6% copper-potassium dichromate-borax solution (CCB), and 2-3% borax all represent efficient options for post-harvest pest control.
